    2.2.3 Machine home position After turning on the machine, all components are set to “home position” if the seat contact switch is actuated (closed). The lifting elements will be raised if they have not already been switched off via the micro-switch for the upper end position integrated in the lifting element (squeegee) or the upper end position is detected by the control unit via the integrated potentiometer.

  • Page 23: Seat Contact Switch (3.6.6.4.)

    2.2.4 Seat contact switch (3.6.6.4.) The seat contact switch (S05) is connected to the control electronics A1 at A1:X9.8+18 and A1:X9.3+13. The control electronics (A1) responds to the relief of the seat with an approx. 2 second delay. This means: If the contact at A1:X9.8+18 is opened for longer than 2 seconds during machine operation, the motors stop and the brush head and the squeegee are raised.
  • Page 24 2.2.4 Seat contact switch (3.6.6.4.) To reactivate the machine after triggering “seat switch manipulation”, the machine control unit must “register” the change of the switch status or the change between ‘operator is sitting on the machine’ and ‘operator has left the seat’. To achieve this, the seat contact switch must be opened and closed several times while the machine is on.
